What I mean is this Alex T,

Remove the collapsibility capacity from the Block Header and let it be as in the Dolphin

Then Let the high content fields like "Textarea" come with collapsibility by default, so when it has content it will be displayed and collapsed, 

When it is empty it will not be displayed and if nothing is displayed under a particular Block Header, it will also not be displayed as it used to be with Dolphin.

The Block Header in Dolphin used to disappear when the Block has no content, so we can have that Header Block without collapsibility + collapsible fields. Knowing fully well that when don't come up the Block headers will not also come.

See the screenshots 1 is what it looks like

Shot 2 is the empty collapsed Header

The 2 doesn't look great
